Roof Rat Populations In Santa Clara County, California, Dean H. Ecke

Vertebrate Pest Conference Proceedings: 2nd (1964)

Northern Santa Clara County, California, was historically an agricultural community with orchard culture dominating the economy. Prunes, apricots, walnuts, and cherries were the principal crops. Orchards were disced clean during most of the summer growing season, and a cover crop of mustard or horse beans was grown beneath the trees in winter. About the only "natural" year around cover on the valley floor was the brush and grass which volunteered along the several creek banks. Under such conditions, roof rats (Rattus rattus) were not numerous. An occasional rat colony could be found in a fruit processing shed or …

Animal Population Ecology And Control Fundamentals, Kenneth E. F. Watt

Vertebrate Pest Conference Proceedings: 2nd (1964)

Expensive, extensive and apparently lethal control measures have been applied against many species of pest vertebrates and invertebrates for decades. In spite of this, few pests have been annihilated, and in many cases the stated goals have become progressively more modest, so that now we speak of saving foliage or a crop, rather than extermination. It is of interest to examine the reasons why animals are so difficult to exterminate, because this matter, of course, has implications for the type of control policy we pursue in the future. Also, it has implications for the problem of evaluating comparatively various resource …

The Role Of Industry In Developing New Materials For Vertebrate Pest Control, G. Hermann, W. M. Zeck

Vertebrate Pest Conference Proceedings: 2nd (1964)

In the first paper presented to you today by Dr. Spencer, an expert in the Animal Biology field and an official authority at the same time, you heard about the requirements imposed on a chemical in order to pass the different official hurdles before it ever will be accepted as a proven tool in wildlife management. Many characteristics have to be known and highly sophisticated tests have to be run. In many instances the governmental agency maintains its own screening, testing or analytical programs according to standard procedures. It would be impossible, however, for economic and time reasons to work …

The American Eagles And Their Economic Status, E. R. Kalmbach, Ralph H. Imler, Lee W. Arnold

United States Fish and Wildlife Service: Publications

For centuries eagles have captured the fancy of man the world over. Because of its extensive range in the northern hemisphere, the golden eagle is the most widely known of this group of birds. Its use in falconry was the sport of kings. The frequency of its appearance in royal coats of arms indicated its importance. It is the national emblem of Germany and Mexico.

In North America the bald eagle as well as the golden eagle represents this group of powerful birds of prey. The bald eagle is strictly an American species, and the founders of the United States …

Waterfowl Drive-Trap Banding, Gene Goecke

Other Publications in Wildlife Management

During a 3-week period in July of 1964, Game Section personnel with assistance from Biology Section and Conservation Officer personnel carried out drive-trap waterfowl banding operations on marsh areas in the northern part of Iowa. This was the fourth year that drive-trap banding operations have been carried out in the state. Several days prior to the actual banding operations were spent selecting areas to band. Areas were selected that had a good population of local birds and vegetative cover suitable for banding. Young birds can be extremely difficult to drive on heavily vegetated marshes of emergent vegetation, and marshes lacking …

Viral Infections Of Domestic Animals, George A. Young

School of Veterinary and Biomedical Sciences: Faculty Publications

There is a strong tendency in current research on mammalian virus diseases to concentrate on virus activity at a cellular or subcellular level. This trend is summarized adequately by Enders in relation to viral replication as follows: ','The large and ever-increasing volume of published experimental work on viral replication strikingly reveals the central position of this phenomenon in contemporary virological research. There are good reasons, both biological and practical, underlying this intensive effort to understand, i n detail, how a virus particle, without energy transforming apparatus of its own, manages to utilize the metabolic equipment of the cell to produce …

Recent Limnological Studies Of The Alkaline Lakes In Nebraska And North Dakota, D. B. Mccarraher

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

Environmental relationships and biological indices have been recorded for 1,200 sandhills lakes in Nebraska since 1954. Three lakes in central and southern North Dakota were investigated during the years 1963 to 1964. Most of the Nebraska lakes were alkaline eutrophic of the sodium bicarbonate and sodium + potassium carbonate types. The North Dakota lakes range from sodium bicarbonate to sodium sulfate types. These lakes may be classified as saline eutrohpic. The ionic composition differs from that of the marine and inland sodium chloride type of water. The invertebrate fauna of permanently alkaline environments are discussed from the point of view …

These records have been subjected to statistical summarization and analysis.

Hyperparasitism, Michael G. Boosalis

Department of Plant Pathology: Faculty Publications

Much of the research on hyperparasitism has been of a descriptive nature, based primarily on studies with dual cultures in synthetic media. The main contributions from these investigations concern the host range of the parasite, the mode of penetration and infection, and the morphological changes of the host and the parasite resulting from parasitism.

More recent studies on hyperparasitism emphasize the effect of environmental factors, especially nutrition, on the susceptibility of the host. Research on the physiology of hyperparasitism has been limited. Nevertheless, this important aspect of the problem should continue to receive increased attention as hyperparasitism is extremely amenable …

The Magnetocardiogram A New Approach To The Fields Surrounding The Heart, R. A. Stratbucker, C. M. Hyde, S. E. Wixon

Department of Electrical and Computer Engineering: Faculty Publications

Experiments have been conducted which reveal the existence of a detectable magnetic field associated with cardiac electrical activity. The relationship between the magnetic record and the electrocardiogram has been explored and it is shown that under certain conditions of axis orientation the voltage induced into a toroidal sensing element around the heart has the form of the first time derivative of the electrocardiogram. A formula based on Maxwell's equations has been developed to relate these two phenomona.

A Review Of The Genus Echinococcus Rudolphi, 1801, Robert L. Rausch, George S. Nelson

Harold W. Manter Laboratory of Parasitology: Faculty Publications

1. The genus Echinococcus Rudolphi, 1801, is reviewed. The recorded measurements of all species are shown in tables, and their taxonomic status is discussed.

2. Three species of Echinococcus can be distinguished by morphological criteria and are considered valid: E. granulosus, E. multilocularis and E. oligarthrus. The status of E. felidis and E. patagonicus is uncertain, but both may be conspecific with E. granulosus. Six species are considered synonyms of E. granulosus: E. cameroni, E. intermedius, E. longimanubrius, E. lycaontis, E. minimus and E. ortleppi.

Echinococcus Infections In Man And Animals In Kenya, George S. Nelson, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

1. Hydatid cysts are found in more than 30 per cent of all cattle, sheep and goats in Kenya, but the disease is prevalent in man only in the semi-desert area of Turkana. Up to the time of the present investigation the life-cycle of the parasite in East Africa had not been studied, but it was suggested that wild carnivores, such as hyenas and jackals, might be the main hosts of the adult worms.

2. One hundred and forty-three carnivores, representing 23 species, have been examined. Echinococcus adults were found in 27 out of 43 domestic dogs (Canis familiaris …

The Inhibition Of Seedling Growth By Crop Residues In Soil Inoculated Wlth Penicillium Urticae Bainer, D. E. Behmer, T. M. Mccalla

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

In the Great Plains area of the United States, stubble-mulch practices have been widely used in the control of soil erosion by wind or water. Although this method of leaving crop residue on the surface has been very effective in combating erosion, depressed plant growth and reduced grain yield have often occurred in wet years. Similar growth problems have been observed during unseasonably cool, wet springs in field experiments at Lincoln, Nebraska. Because increased numbers of certain micro-organisms occur immediately beneath a decomposing surface mulch, the production of phytotoxic compounds under these conditions may well have been associated with the …

Alveolar Hydatid Disease Of The Liver: Rationale And Technics Of Surgical Treatment, John T. West, F. J. Hillman, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Cestodes of the genus Echinococcus cause two distinct diseases: the well-known cystic hydatid disease found in stock-raising areas, caused by E. granulosus, and the more rare alveolar hydatid disease, which is limited to the northern hemisphere and is caused by the biologically and morphologically distinct E. multilocularis.

Eight cases of alveolar hydatid disease of the liver are reported from Alaska, including three patients who underwent hemihepatectomy for advanced lesions. Radical resection is concluded to be the only rational treatment for this otherwise progressive and fatal disease.

Ticks (Ixodidae) On Birds Migrating From Europe And Asia To Africa, 1959-61, Harry Hoogstraal, Makram N. Kaiser, Melvin A. Traylor, Ezzat Guindy, Sobhy Gaber

United States Navy: Publications

The need for imaginative thinking and research in the epidemiology of diseases transmitted by arthropods is made manifest by new views of the longevity and host ranges of arthropod-borne viruses, as well as by other biological and medical phenomena. Among these is the intercontinental transport of ticks by migrating birds. During the fall migration periods of 1959, 1960 and 1961, 32 086 birds (comprising 72 forms) were examined for ticks in Egypt while en route from Asia and eastern Europe to tropical Africa. Of these, 40 forms, represented by 31 434 birds, were tick-infested. The bird hosts, numbering 1040 (3.31% …

The Bdellidae (Acarina) Of The Australian Realm, Warren T. Atyeo

Bulletin of the University of Nebraska State Museum (1924–2023)

Although primarily a systematic study, variations in the integumental striae and chaetotaxy of the legs are discussed. The genus Octobdellodes Atyeo, 1960 is synonymized with Bdellodes Oudemans, 1937 and the sugenus Cytobdella Mihelcic, 1958 is synonymized with Cyta von Heyden, 1826. The genus Bdellodes is divided into the subgenera Bdellodes and Hoploscirus Thor, 1937 (=Thoribdella Grandjean, 1938, new synonymy). Twenty-two species are now known to occur in New Zealand and the outlying islands. These include four known species: Bdella iconica, Bdellodes (Roploscirus) lapidaria, B. (R.) reticulata, and Cyta latirostris, and eighteen new species: Bdellodes (Bdellodes) harpax, B. (B.) oraria, …
